When do I Replace an Ink Cartridge in the HP Photosmart C7280 All-in-One Printer?

Your HP Photosmart C7280 All-in-One Printer is equipped with six ink cartridges: Black, Cyan, Magenta, Yellow, Light Cyan, and Light Magenta. The installed ink cartridges are consumable components, which will become exhausted/emptied eventually. You could check the status of each installed ink cartridge by opening the [Ink Gauge] menu – [Setup] – [Tools] – [Display Ink Gauge]. You must replace an indicated ink cartridge or several indicated cartridges, if any of the listed and described below messages appears on the control panel display.

• ‘’Cannot Print <Color>’’, ‘’Original HP ink depleted’’, or ‘’Ink cartridge(s) are empty <Color>’’ – The indicated ink cartridges have been completely emptied/exhausted. Your HP Photosmart C7280 All-in-One Printer is in a non-operational mode, which means that all print operations are disabled. The only available action is the replacement of all indicated ink cartridges.

• ‘’Calibration error’’ – The automatic ink cartridges calibration cannot be performed, because the paper loaded into the input tray is from an unsupported type. You must load a supported paper type/size.

• ‘’Incorrect ink cartridge(s)’’ or ‘’Wrong ink cartridge(s) installed’’ – The indicated ink cartridge has been inserted into a wrong ink cartridge slot, or the cartridge type is unsupported. You must make sure that the ink cartridges are correctly installed.

• ‘’Ink cartridge(s) problem’’ – The built-in monitoring system is not receiving data from the sensors of the indicated ink cartridges. You must make sure that the specified ink cartridges are correctly installed. Please replace the problematic ink cartridges, if the problem persists.

• ‘’Ink expiration near’’ or ‘’Ink cartridge(s) are expired <Color>’’ – Each installed ink cartridge has a certain expiration date, after which the print quality cannot be guaranteed. Therefore, you should reinstall all indicated ink cartridges soon after the initial appearance of this expiration-warning message.

• ‘’Non-HP ink’’ – This message indicates that the specified ink cartridges are not manufactured by HP. You should press the [GO] button to continue printing using the non-HP ink cartridges. No further actions are required in this situation.

• ‘’Alignment failed’’ – The ink cartridges alignment cannot be performed, because there is photo or color paper loaded in the input tray. You should load plain white letter or A4 paper into the input tray to resolve the issue.

• ‘’Replace ink cartridge(s) <Color> soon’’ – This is an advance notification, which is indicating that the specified ink cartridges will be completely emptied very soon. You should install new ink cartridges of the indicated colors soon after the initial appearance of the warning message on the control display.

It is always better, if you keep a spare set of ink cartridges for your HP Photosmart C7280 All-in-One Printer in stock, but please remember to store these consumable components in accordance with the manufacturer’s instructions and recommendations. Please follow the instructions given below to replace the exhausted ink cartridge/cartridges in your HP thermal ink-jet printer.

How to Install an Ink Cartridge in the HP Photosmart C7280 All-in-One Printer

Please make sure that your HP Photosmart C7280 All-in-One Printer is in a ‘’Stand-by’’ (‘’Ready’’) mode, and then open the cover of the ink cartridges compartment. After that, you must locate the exhausted ink cartridge by checking the labels, and then unlock the exhausted cartridge by pulling the lock lever of the corresponding slot upwards. Once the old cartridge is unlocked, you must remove it from the ink cartridges compartment by carefully pulling it towards you, and then unpack the new ink cartridge of the corresponding color. Please avoid shaking the used/exhausted ink cartridges. Now, you must insert the unpacked new ink cartridge into the corresponding slot of the ink cartridge compartment. Finally, you must lock the new ink cartridge into place by pushing the lever of the corresponding slot towards the main unit, and then close the cover of the ink cartridges compartment.
